![]() ![]() I'm not entirely sure what I'm doing is best practice but the way joins work are actually backwards in terms of the way I want to use them here, efficiently speaking (I wish I could flip the left and right queries but that doesn't work). Side note - I use a subsearch initially on the left side of the join because it would be too much data to feed into the right side without it. join does not accept a where clause nor does it have left or right options. I imagine any other fields that share a name would only get the right side's value as well but I haven't tested. asked at 5:09 ThomasWest 485 1 6 21 Add a comment 1 Answer Sorted by: 0 From your example queries I guess you are an experienced SQL user who is new to Splunk and hasnt read the manual about the join command. To use the join command, the field name must be the same in both searches and it must correlate to two data sets. What is the Join Command in Splunk The join command brings together two matching fields from two different indexes. When a search contains a subsearch, the subsearch. The answer is yes In these cases, we can use the join command to achieve the results we’re looking for. The search ONLY returns matches on the join when there are identical values for search 1 and search 2. Ive tried using the 'search' command and 'foreach' command, but have had no joy. To return all of the matching subsearch rows, include the max. In Splunk, the primary query should return one result which can be input to the outer or the secondary query. Run the event log query for users that exist in the array, e.g.: using semantics such as isin () or contains () or ii) Enumerate the group members and perform a foreach () type loop. It displays the expected data, almost! However, values(sourcetype) is only returning "dns" as a value! Join is not pushing the sourcetype value of "http" into the events, even though all of the other http fields are being joined correctly and displaying in the stats output. By default, only the first row of the subsearch that matches a row of the main search is returned. Now, I've been attempting to replicate this in a splunk query and have run into quite a few issues. ![]() above means be deemed advisable, to join any expedition for the above purpose. | stats values(dns_answer) values(http_uri) values(http_response) values(sourcetype) dc(sourcetype) values(_time) count by http_domain select a.firstname as first1, a.lastname as last1, b.firstname as first2, b.lastname as last2, b.date as date from myTable a inner join myTable b on a.id b.referrerid Which returns the following table, which gives exactly the data I need. The first general meeting of this company took place ou Thursday last. Tried using lookup in subsearch with no luck. I cannot edit the nf for maxmatches entry as I dont have admin access. This join almost works: index=customer_1 sourcetype=http Here, in this code, because the top Command returns the fields of count and percent, the table command retains only the clientip value. I cannot use a join for the lookup as the number of entries even if i dedup is more than 600k. I have discussed their different use cases in details.you. Lookup: Use to add fields from the lookup file file into your search result. In this video I have discussed about three commands 'join', 'map' and 'selfjoin'. ![]() Just a subsearch will not achieve what I want here due to the way I want to stats the data out. Explanation: As you know in the previous step we uploaded a lookup file name statuscode.csv, by using the inputlookup command we are viewing the content of that lookup file as simply as you see. ![]() Splunk Cheat Sheet Reference Guide Pdf Submit Your Queries. The problem is that the join only returns the first match even though the max=0 setting is set.I need to join data from two (or more, ultimately) different sourcetypes based on the shared "host" field. Use the fields command to return only the operation, JSESSIONID, and status fields. Then if any rows that have that persistent_id have turned up in the last 2 days it joins them to the Applicant table and returns a table result with the audit id and the names It first selects any rows from the audit table that have a not null persistent_id that occurs in the table more than 20 times. ![]()
